Title: Position controller
Inventor: SHIYOUJI ATSUSHI
IPC: G05D3/12
Filed: 1991-04-25
Abstract: PURPOSE:To suppress mechanical vibration generated at each stop for positioning as to the position controller used for an NC machine tool or robot. CONSTITUTION:A machine system which rotates a motor with a speed command obtained by accumulating the difference between a position command signal supplied in pulse unit for a unit time interval and a position feedback signal supplied at a unit time interval has a decision circuit 8 which decides cases wherein the accumulation output of the difference between the position command signal pulses and position feedback pulses is $1/2 time as large as the minimum unit of position detection and a switch 9 which cuts off the output of an accumulator 2 when the position deviation is <=1/2 time as large as the minimum position detection unit. This machine system which uses an encoder 6 with optional resolution and sets and uses various gear ratios suppresses vibration generated before and behind a command stop position to stably stop the object.

Abstract: PURPOSE:To attain normal recording of a video signal by providing a 1st modulator receiving an output signal from a digital signal processing unit as a modulation input and supplying a modulation signal to a 1st recording and reproducing means and a 2nd modulator converting an inputted video signal into a luminance signal subject to frequency modulation and a color signal subject to low frequency conversion and supplying the converted signal to a 2nd recording and reproducing means. CONSTITUTION:A 1st signal processing unit 9 adds an error correction code to an inputted digital audio data and applies signal processing such as formatting and supplies the result to a 1st modulator 10. The 1st modulator 10 converts an input signal into a 4-phase modulation signal taking a frequency band shown in figure H into a 2.5MHz carrier frequency and gives the result to a 1st amplifier 11. A video signal fed to a 2nd input terminal 16 is inputted to a 2nd modulator 17, in which the signal is separated into a luminance signal and a chrominance signal and they are subject to frequency modulation and low frequency conversion respectively in a frequency band shown in figure I. The luminance signal subject to frequency modulation and the chrominance signal subject to low frequency conversion are added and the result is fed to a 2nd amplifier 18.

Title: Cache memory device
Inventor: TAKAHASHI KAZUNORI
IPC: G06F12/12
Filed: 1990-04-11
Abstract: PURPOSE:To reduce the overhead to the mishit by reading N pieces of valid flags (N>1, N:integer) at the same time to an entry address. CONSTITUTION:The tag read out of a tag part 2 is compared with a higher rank (tag data) of an input address 1 by a comparator 5, and the result of this comparison (tag coincidence signal 16) is inputted to a control means 9. The four valid flags read out of a valid flag part 3 are stored in a valid flag latch 6. At the same time, the first data on an entry is read out of a data part 4 and stored in a data latch 7. The means 9 immediately outputs a memory read request signal 19 when the coincidence of tags is discriminated by the signal 16. Then the means 9 updates the tags and resets the valid flags in the next cycle. When the coincidence of tags is secured, the hit/mishit of a cache is discriminated based on the contents of the latch 6. When the mishit is detected, the signal 19 is outputted. Thus the overhead is reduced at the time of mishit.

IPC: C30B23/08
Filed: 1983-05-31
Abstract: PURPOSE:To stabilize the intensity of a molecular beam for a long time and to decrease considerably the consumption of a sample until said intensity stabilizes by detecting the intensity of the molecular beam emitted from a molecular beam source and controlling the heating electric power for the molecular beam source so that the detected value is maintained at a prescribed value.

Title: Device for controlling defrosting of air heat source heat pump
Inventor: ONO YASUO
IPC: F25D21/10
Filed: 1990-04-13
Abstract: PURPOSE:To reduce heat loss induced by radiation and save energy by changing heating speed of a heating liquid medium (hot water or anti-freeze solution) in a heat storage tank and matching defrost timing with heat storage timing in the heat storage tank. CONSTITUTION:This control system comprises a temperature detector 7 which detects the temperature a heating solution medium in a heat storage tank 3 and a humidity detector 31 which detects the humidity of open air. This system is also provided with a control circuit which changes the electric current flowing to a heater 5 designed to heat the heating solution medium in the heat storage tank, responding to the humidity condition detected by the humidity detector 7. The control device is provided with a temperature switch 8 which switches on or off based on the heating solution temperature detected by the temperature detector 7. The growth speed of frosting to heat transfer tubes of a heat exchanger is determined by the humidity of open air (wet bulb temperature) and the surface temperature of the heat transfer tubes. The heating temperature is controlled so that the temperature of the heat storage tank may reach the temperature at which the heat storage has been completed at the starting time of defrosting. It is, therefore, possible to reduce the amount of radiation from the heat storage tank at low temperature when longer time is called for before the start of defrosting.

IPC: H04N1/04
Filed: 1986-04-25
Abstract: PURPOSE:To accurately stabilize the light quantity of a light source in a short time, by providing a reference body and irradiating the light of the light source upon the reference body, and then, discriminating whether the light quantity of the light source is stabilized or not on the basis of the reflecting light quantity from the reference body whether the light quantity reaches a set value or not. CONSTITUTION:When electric power is supplied to the main body of this exposing and scanning device, a main control section 41 makes a fluorescent lamp 23 to light and, at the same time, turns on a heater 43. A carriage 22 is moved to the scale 13 side of an original placing table 12 and rays of light are irradiated upon a reference body provided on the backside of the scale 13. The rays of light reflected by the reference body 32 are stored in a line memory 47 after they are converted into digital data through a line sensor 25 and AD converter 29. Then the mean value of the data stored in the memory 47 is calculated and whether or not the mean value exceeds a preset value is discriminated. When the mean value does not reach the preset value, whether a prescribed time has passed or not is discriminated. When the prescribed time has not passed, discrimination of the mean value is continued. When it is discriminated that the mean value exceeds the preset value, it is discriminated that the light quantity of the light source is stabilized. Thus the light quantity of the light source can accurately be stabilized in a short time.

Filed: 1981-06-24
Abstract: PURPOSE:To increase dielectric strength by providing a buried layer with high impurity density under the source region of an offset gate type MOSFET and a region including a gate. CONSTITUTION:A P<++> type buried layer 11 with high impurity density is provided under the N<+> type source region 5 of an offset gate lateral type power MOSFET having an N<-> type high dielectric strength layer 6 and a region including a gate 4.
